idle adjust
i'v got a 98 f150 4.2 v6 AT just wondering if there's a way to adjust my idle control? at Nuetral i idle at 900rpm i believe it should be around 7.5rpm

No. It's PCM controlled. It's possible that yer IAC is in need of replacement ( cleaning them seldom works for long for whatever reason). Mind you this is from what I see on a V8 of that vintage - may want to wait until a 4.2 guru cimes in - it may be different. Good luck.
EDIT - not much, but I did find this: https://www.f150online.com/forums/v6...3-f-150-a.html
